Bug 489362

SUMMARY
When resuming work on my laptop after sleep / closing the lid, sometimes the touchpad is unrensponsive and requires two fingers to move the pointer.


STEPS TO REPRODUCE
1. Work with your laptop normally
2. Close the lid 
3. Open the lid
4. Go through 1-2-3 a few times until the problem appears.

OBSERVED RESULT
The touchpad does not respond to the usual one-finger operation, while using two fingers can move the cursor.

EXPECTED RESULT
The touchpad works normally.

ADDITIONAL INFORMATION
I observed this behaviour on the GNOME Session as well, but I never experienced on Plasma X11. This could point to an upstream issue (Wayland).

Switching to a virtual terminal and then back to the desktop fixes the issue. Similar issues have been reported in the past 2+ years across several platforms: https://askubuntu.com/questions/1387034/touchpad-starts-requiring-2-fingers-way-to-fix
